I just finished viewing Scott Hossack's presentation on sustainable blogging. It really was full of some excellent ideas on how to start and maintain student blogging in the classroom. He makes a very good point that adding blogging to what you already do in the classroom is not a recipe for success. We need to do something different in order to incorporate blogging with students, otherwise it will fall by the wayside. Scott mentioned that blogs should not be looked at as journals-they should be looked at as an opportunity for students to read, connect, communicate, reflect and comment on the blogs of others.
He had great practical ideas as well. Students should start out with blogging by simply reading the blogs of other students. A teacher can use netvibes or iGoogle to gather some blogs for students to start with and then share these blogs for them to access.
I think the realm of student blogging is an exciting one and hopefully we'll be able to delve into this on a much broader and deeper level at University School.
